The utility model provides a frock is played to this kind of PC prefabricated plate, including H shaped steel gallows and supporting hoist, H shaped steel gallows includes two parallel arrangement's H shaped steel and a plurality of connection shaped steel between them. The lifting appliance comprises two pairs of plug-in main bodies and two steel wire ropes, the plug-in main bodies comprise two support legs for clamping H-shaped steel webs and connecting pieces between the two support legs, the plug-in main bodies are respectively inserted into two ends of the H-shaped steel in a mode that the two support legs clamp the H-shaped steel webs, the steel wire ropes are connected between the connecting pieces of the two plug-in main bodies at the same end, and after a hoisting object is arranged on an H-shaped steel hanging bracket, hoisting equipment hooks a hoisting ring on the steel wire.
In an embodiment of the above technical scheme, two legs of the plug-in main body are made of rectangular steel plates, a rectangular groove is formed in the middle of the lower side of the length direction of the two legs, the length direction side edge of an entity at one end of the rectangular groove is an adduction bevel edge, a round hole is formed in the entity at the other end of the entity, and the bevel edge end serves as the inner end of the plug-in main body.
In an embodiment of the above technical scheme, the connecting member is a circular steel tube, and two ends of the connecting member are respectively welded in the circular holes on the two legs of the plug main body.
In an embodiment of the above technical solution, when the steel wire rope is connected to the plug main body, the steel wire rope passes through an inner hole of the connecting member.
In one embodiment of the above technical solution, a soft rubber pad is bonded to the oblique edge of the lower side of the leg.
The utility model discloses the web of gallows H shaped steel is held through two landing legs to the grafting main part of hoist, and each grafting main part is two-way atress when making the prefabricated plate body lift by crane, guarantees that the hoist atress is even, and the hypotenuse of adduction is in the front end bottom surface of two landing legs of grafting main part in addition, when making lift by crane and H shaped steel between the pterygoid lamina form the face contact, increase frictional force to avoid the handling in-process grafting main part from H shaped steel department landing, improve the security of handling in-process.

Detailed Description
As shown in FIG. 1, the PC precast slab plays a role of tooling, and comprises an H-shaped steel hanger 1 and a lifting appliance 2.
As can be seen in conjunction with fig. 1 to 3:
the H-shaped steel hanger 1 comprises two H-shaped steels 11 arranged in parallel and a plurality of connecting section steels 12 between the two H-shaped steels. The connecting section steel 12 of this embodiment is also H-shaped steel of the same type.
As can be seen in conjunction with fig. 1 to 5:
the lifting appliance 2 comprises two pairs of inserting main bodies 21, two steel wire ropes 22 and lifting rings.
The plug-in main body 21 comprises two legs 211 for clamping an H-shaped steel web and connecting pieces 212 between the two legs, each plug-in main body 21 is respectively inserted into two ends of the H-shaped steel 11 in a mode that the two legs clamp the H-shaped steel web, a steel wire rope 22 is connected between the connecting pieces of the two plug-in main bodies 21 at the same end, and the hanging ring is fixed at the middle position of the two steel wire ropes 22.
Two landing legs 211 of grafting main part 21 all adopt the preparation of rectangle steel sheet, and there is the rectangle recess in the middle part of its length direction downside, and the length direction lateral edge of rectangle recess one end entity has seted up the round hole for the hypotenuse of adduction, other end entity, and the hypotenuse end is as the inner of grafting main part 21.
The connecting member 212 is a circular steel tube, and two ends of the connecting member are welded in the circular holes of the two legs 211 respectively.
The cable 22 passes through the inner hole of the connector 212 when connected to the plug body 21.
A soft rubber pad (not shown) is bonded to the lower side of the leg 211 at the oblique edge.
After the PC prefabricated plate body is conveyed to the H-shaped steel hanging bracket, the plug-in main bodies of the hanging device are respectively inserted into two ends of two H-shaped steels, and the hoisting equipment is hoisted through the hoisting rings.
Because the web of gallows H shaped steel is held to the grafting main part of hoist through two landing legs, each grafting main part is two-way atress when making the prefabricated plate body lift by crane, guarantees that the hoist atress is even, and the front end bottom surface of two landing legs of grafting main part is the hypotenuse of adduction moreover, and hypotenuse department sets up soft rubber pad, forms the face contact when making to lift by crane between the pterygoid lamina with H shaped steel, increase frictional force to avoid the handling in-process grafting main part to follow the landing of H shaped steel, improve the security of handling in-process.
